摘要
LED点阵显示屏是利用发光二极管点阵模块和像素单元组成的平面式显示屏。以单片机为核心控制器、以基本单元模块8×8点阵为主要分析对象,阐述了LED显示屏点阵结构的矩阵分布特征、显示扫描时元素点取值的矩阵特性以及点阵大小不同的显示屏在扩展中呈现的矩阵规律性。结果表明:在显示控制技术和产品设计方面应以矩阵模型特性为主来有效控制电子领域广泛使用的LED点阵显示屏。
LED lattice display screen is a kind of flat display screen consisting of light-emitting diode lattice modules and pixel units. Taking single-chip microcomputer as core controller and the basic 8 ~ 8 lattice module as analysis target, this paper elaborates the matrix distribution characteristics, the matrix characteristics of the picture element values during the reading scan and the matrix rules reflected in the extension of display screen with different lattices. It indicates that the characteristics of the matrix module should be mainly adopted in the display controlling technology and the product design to effectively control the LED lattice display screen widely used in the electronic domain.
